It takes all 3 to maximise conditioning, physical and mental performance. To a backdrop of mixed internationally acclaimed music, you’ll target select muscle-groups.

Tri Session In Detail

TRI is Sheffield’s new benchmark in physical and mental evolution through exertion.

A TRI session will consist of 33% high intensity interval training on the treadmills, 33% resistance training on the floor and 33% high intensity floor work training/pad work. The other 1%? Well, we might let you rest.

You’ll work with dumb-bells, medicine balls, resistance bands, kettle-bells, Grapple bags and good old bodyweight. Choose the class format to suit you, all with music playlists to maximise your workout...and help mask your screams.


Give it your all and we guarantee you’ll burn somewhere between 700-1000 calories. Workout at 75% and you’ll still say goodbye to 300-500 calories. They’re serious figures that deliver one serious figure.
